This parameter is used to set the proportional
coefficient of the bus voltage regulator during
undervoltage stall.
Setting range: 0–1000
This parameter is used to set the integral
coefficient of the bus voltage regulator during
undervoltage stall.
Setting range: 0–1000
This parameter is used to set the proportional
coefficient of the active current regulator during
undervoltage stall.
Setting range: 0–1000
This parameter is used to set the integral
coefficient of the active current regulator during
undervoltage stall.
Setting range: 0–2000
This parameter is used to set the proportional
coefficient of the bus voltage regulator during
overvoltage stall.
